OBJECTIVE
To assess the relationship between air pollution and respiratory morbidity.
DESIGN
An ecological study of the daily hospital admissions abstracted for the 1988 calendar year. Air quality data, including nitrogen dioxide (NO2), sulphur dioxide (SO2), ozone (O3) and particulates, were obtained from the relevant authorities.
SETTING
Latrobe Valley, Victoria.
SUBJECTS
Hospital admissions for asthma and Chronic Obstructive Airways Disease. (COAD).
RESULTS
There were significant associations (r = 0.11 to 0.17) between airborne particles, nitrogen dioxide and respiratory morbidity. There was no significant relationship between any of the pollutants and asthma admissions. However, multi-variate analysis confirmed that NO2 and particulates were associated with admissions for COAD.
CONCLUSION
Respiratory morbidity appears to be affected even by the low air pollution levels in the Latrobe Valley.
目的
评估空气污染与呼吸道疾病发病率之间的关系。
设计
对1988年全年医院每日住院病例摘要进行的一项生态学研究。空气质量数据，包括二氧化氮（NO₂）、二氧化硫（SO₂）、臭氧（O₃）和颗粒物，从相关部门获取。
地点
维多利亚州拉特罗布谷。
研究对象
哮喘和慢性阻塞性气道疾病（COAD）的住院病例。
结果
空气中的颗粒物、二氧化氮与呼吸道疾病发病率之间存在显著关联（r = 0.11至0.17）。任何一种污染物与哮喘住院病例之间均无显著关系。然而，多变量分析证实，二氧化氮和颗粒物与COAD的住院病例有关。
结论
即使拉特罗布谷的空气污染水平较低，呼吸道疾病发病率似乎也受到了影响。
